1. Jenny is organising a barbecue. There are 30 bread rolls in a pack. There are 16 sausages in a pack. She needs exactly the same number of bread rolls as sausages. What is the smallest number of each pack she must buy?
Answer:
2. Tom, Sam and Matt are doing a show by counting drum beats .They decided to donate the collecting money for the poor children for their studies. Tom hits a snare drum every 2 beats. Sam hits a kettle drum every 5 beats. Matt hits a bass drum every 8 beats. Tom, Sam and Matt start by hitting their drums at the same time. How many beats is it before Tom, Sam and Matt next hit their drums at the same time? What value you can see in their act
Answer:
If you answer I promise I will make you the brainiest, like and I will vote 5
Answer:
Step-by-step explanation:
First find the LCM of 30, 16. This will give the common number of sausages and bread rolls
30 = 2 * 3 * 5
16 = 2 * 2 * 2 * 2
LCM = 2* 2 * 2 * 2 * 3 * 5 = 240
240 sausages and 240 bread rolls
Number of Sausage pack = 240 ÷ number of sausages in a pack
= 240 ÷ 16
= 15
Number of bread roll pack = 240 ÷ number of bread rolls in a pack
= 240 ÷ 30
= 8
Jenny should buy 8 pack of bread rolls and 15 pack of sausage
2) LCM of 2 , 5 , 8 = 40
Tom, Sam, Matt will hit their drum same at 40 minutes
Number of beats hit by Tom before reaching 40 minutes = 40/2 =20 hits
Number of beats hit by Sam before reaching 40 minutes = 40/5 = 8 hits
Number of beats hit by Matt before reaching 40 minutes = 40/8 = 5 hits

M is the midpoint of PQ.
PM = 5x + 8 and PQ = 76, find x.
(2 Points)
Enter your answer
Answer: x=6
Step-by-step explanation:
Just think about how the problem is half
The value of x is 6.
Here,
M is the midpoint of PQ.
PM = 5 x + 6
PQ = 76
What is midpoint of line?
The midpoint is the middle point of a line segment. It is equidistant from both end points.
Now,
M is the midpoint of PQ.
Hence, PM = MQ
And, PQ = PM + MQ
⇒ PQ = 2 PM
⇒ 76 = 2 (5x + 8)
⇒ 38 = 5x + 8
⇒ 5x = 30
⇒ x = 6
Hence , The value of x is 6.

Solve for a. Show (All steps must be shown): -2(a-3)=12
Answer:
a= -3
Step-by-step explanation:
first distrubute the parenthesis -2(a-3)
-2a+ 6= 12
then move the like terms
6 becomes -6 and subtract to both sides so 6-6 cancels out and you are left with 12-6 which gives you 6
then you have -2a = 6
lastly divide on both sides and you get
-2a÷ -2 (cancels out)
6÷ -2
and the answer is
a= -3

Step-by-step explanation:
105 degrees is from a b to d and a b to c is 75 and 105 - 75 =30.
Answer:
30*
Step-by-step explanation:
If ABD is 105* then it would be <ABC+<CBD=105*. We know that <ABC is 75* so we can fill that in. 75*+<CBD=105*. Then we solve.
75* + <CBD = 105*
-75* -75*
<CBD=30*
So that's how I got it.

b is a point between a and c where ac = 5x, ab = 12, and bc = 3x + 2. what is the measure of the length of ac?
Answer:
AC=22
Step-by-step explanation:
The measure of the Length of AC is; 35
We are given;
ac = 5x
ab = 12
bc = 3x + 2
We are told that b is between a and c. This means that;ab + bc = ac
Thus;
12 + 3x + 2 = 5x
14 + 3x = 5x
Subtract 3x from both sides to get;
5x - 3x = 14
2x = 14
x = 14/2
x = 7
Thus, ac = 5x = 5 * 7ac = 35

Mr. Peter's has 80 sheets of colored paper seven of his students need it for a project. how many sheets are left over?
Answer:
Three sheets will be left over.
Step-by-step explanation:
Well, if you have 80 sheets of paper, and seven students need it, you would first divide the 80 sheets to the seven students using the equation 80 ÷ 7 = 11.4. You won't be giving fractions of paper to the students so you would round to 11. If each of the seven students gets 11 sheets of paper, 77 sheets will have been used. 80 - 77 = 3. So, there will be three sheets left over.

Step-by-step explanation:
I don’t get it someone help it’s due in 40 minutes
===========================================================
Explanation:
To find the slope, all you need are two points.
Pick any two columns to form the two points. Once you have your two points, use the slope formula
I'll use the first two columns
m = (y2-y1)/(x2-x1)
m = (12.2-13)/(4-0)
m = -0.8/4
m = -0.2 is the slope
The y intercept is b = 13 since x = 0 leads to y = 13 (column 1)
With m = -0.2 and b = 13, we go from y = mx+b to y = -0.2x+13

107
Step-by-step explanation:
it looks like a right angle
Answer:
The answer is 107 degrees.
Step-by-step explanation:
The sum of all the angle of a triangle must equal 180 degrees. That being said if you grab 180 and subract 44 and 29 from it you get 107 degrees. 107+44+29=180. If this did not equal 180 the answer would be wrong but since it does it is right.

Find the measure of each angle.
(3x + 5)^(10x-7)
The measure of angle TQR is 47 degrees and the measure of angle TRS is 133 degrees
In order to determine the measure of each angle, the value of x has to be determined first
The sum of angles on a straight line is 180 degrees
Thus : (3x + 5)° + (10x - 7)° = 180°
3x + 5 + 10x - 7 = 180
combine similar terms
3x + 10x = 180 - 5 + 7
add similar terms
13x = 182
divide both sides of the equation by 13
x = 14°
Substitute for x in (3x + 5)° and (10x - 7)°
(3x + 5)° = 3(14) + 5 = 47°
(10x - 7)° = 10(14) - 7 = 133°

Laurel ran 3 miles in 24 minutes.At that rate,how long will it take her to run 7 miles?
Answer:
it took her 60 mins which is a hour
Step-by-step explanation:
you would simply add 24 plus 24 and get 48 then u would take 24 and divide that by 2 and get 12 and then u would add 48 and 12 and get the final answer of 60
Answer:
it would take laurel 56 minutes to run 7 miles.
Step-by-step explanation:
She has to run 7 miles, so if she can run 3 in 24 minutes, you can double that time to 48 minutes to run 6 miles, on top of adding another 8 minutes due to 1/3 of 24 (the third being equal to 1 mile since 24 is 3 miles) being 8, leaving you with 56 minutes for her 7 mile run.
Help with G and H plz
Answer: For G the answer is x=30, for H x is 30
Step-by-step explanation:
G. The square means 90 degrees and the equation would be 90+3x=180. Subtract 90 from both sides would give you 3x=90 and divide it by 3 would give you x=30
H. The two lines means that both sides are congruent and so 75x2=150 150+x=180 subtract 150 from both sides would give you x=30
